Description

Data transmission method and device

technical field

The present application relates to the field of communication technologies, and in particular, to a data transmission method and apparatus.

Background technique

In wireless communication networks, extended reality (XR) technology has the advantages of multi-view and strong interactivity, which can provide users with a brand-new visual experience, and has great application value and commercial potential. XR includes technologies such as virtual reality (VR), augmented reality (AR), and mixed reality (MR), which can be widely used in entertainment, games, medical care, advertising, industry, online education, haptics Internet, and engineering.

A characteristic of XR data is that there are certain dependencies between the data. For example, a video frame in XR data can generally be divided into multiple data packets, and if the transmission of one of the multiple data packets fails, the entire video frame may not be received correctly. For another example, in the tactile Internet, information such as video information, tactile information, and control information has dependent synchronization requirements. When the transmission of certain types of information is lost or delayed, it will affect the overall service effect and user experience.

Therefore, how to meet the synchronization requirements between data when transmitting XR data with dependencies, so as to improve the user experience of the XR service, has become an urgent problem to be solved.

In wireless communication networks, XR technology has the advantages of multiple perspectives and strong interactivity, which can provide users with a brand-new experience, and has great application value and commercial potential. XR includes technologies such as VR, AR, and MR, and can be widely used in entertainment, gaming, medical, advertising, industry, online education, and engineering. VR technology mainly refers to the rendering of visual and audio scenes to simulate the visual and audio sensory stimulation of users in the real world as much as possible. VR technology usually requires users to wear XR terminals (such as head-mounted devices) to simulate visual effects to users. and/or hearing. VR technology can also perform motion tracking of the user, thereby updating the simulated visual and/or auditory content in time. AR technology mainly refers to providing visual and/or auditory additional information or artificially generated content in the real environment perceived by the user, where the user's acquisition of the real environment can be direct (eg, without sensing, processing and rendering), It can also be indirect (for example, transmitted through sensors, etc.), and further enhanced processing is performed. MR technology is to insert some virtual elements into the physical scene, the purpose is to provide users with an immersive experience where these elements are part of the real scene. The network device can process and transmit the data generated by the XR service (may be called XR data). For example, the network device in the cloud can render and encode the XR source data (such as source encoding). The connected network equipment transmits the XR data to the XR terminal. The XR terminal provides users with a variety of XR experiences (such as immersive experience, visual experience, interactive experience or device experience, etc.) by processing XR data. There are various evaluation dimensions for XR experience, including one or more of the following evaluation dimensions: picture clarity, picture fluency, picture distortion, picture three-dimensionality, picture black borders, picture smear, sound quality, sound effect, Field of view, stuttering, blurry screen, vertigo, audio and video synchronization, interactive freedom, interactive operation response speed, interactive operation accuracy, interactive content loading speed, terminal wearing comfort, terminal wearing fatigue, terminal battery life , terminal portability, or terminal visual impairment friendliness, etc.

A characteristic of XR data is that there are certain dependencies between the data. For example, a video frame in XR data can generally be divided into multiple data packets, and if the transmission of one of the multiple data packets fails, the entire video frame may not be received correctly. For another example, in the tactile Internet, information such as video information, tactile information, and control information has dependent synchronization requirements. When the transmission of certain types of information is lost or delayed, it will affect the overall service effect and user experience. Therefore, how to meet the synchronization requirements between data when transmitting XR data with dependencies, so as to improve the user experience of the XR service, has become an urgent problem to be solved.

The embodiments in this application provide an integrity transmission method for XR data transmission, in which integrity transmission is performed on data or information with synchronization requirements or dependencies, so as to meet the synchronization requirements between data or information, thereby Improve the user experience of XR services.

In this application, the integrity transmission of data can be understood as the transmission of two or more data units as a whole. Among them, the object of integrity can have many different understandings.

For example, the object of integrity may be content, ie content integrity. Contents of multiple different dimensions have an associated relationship, so the integrity transmission of multiple data units corresponding to the content of multiple dimensions is performed. For example, there is an association relationship between multiple data units corresponding to a picture frame content, a relationship between a basic layer data unit and an enhancement layer data unit corresponding to a picture frame content, and an association relationship between a picture frame data unit and an audio data unit. have associations, etc.

For another example, an object of integrity may also be a task, event, object or class, ie task integrity, event integrity, object integrity or class integrity. Multiple data units in the same task, the same event, the same object, or the same class have an associated relationship, so integrity transmission is performed on the multiple data units in the same task, the same event, the same object, or the same class. For example, in the tactile Internet, there is an association relationship between multiple data units corresponding to information such as video, audio, motion, and touch.

It can be understood that the integrity transmission and integrity objects in this application may also have other descriptions. For example, the above-mentioned integrity transmission can also be described as task-driven transmission, event-based transmission, or object-oriented transmission, etc., which are all within the scope of the present application.
